[media] s5p-mfc: Allocate firmware with internal private buffer alloc function
Once firmware buffer has been converted to use s5p_mfc_priv_buf structure,
it is possible to allocate it with existing s5p_mfc_alloc_priv_buf()
function. This change will help to reduce code variants in the next
patches.
